Pope Francis (L) waves as he is driven inside the Malmo Arena where he is to hold an ecumenical event on October 31, 2016 in Malmo, Sweden. Pope Francis kicked off a two-day visit to Sweden to mark the 500th anniversary of the Reformation -- a highly symbolic trip, given that Martin Luther's dissenting movement launched centuries of bitter and often bloody divisions in Europe. / AFP PHOTO / VINCENZO PINTO
